Choosing 'the best' car battery can be somewhat confusing, since just like cars, car batteries come in various sizes, shapes and also differ in terminal types and orientation, exact chemistry, CCA/MCA features, battery type, etc.
Picking the right battery means having the battery that will do its job for years to come, without leaving the user stranded with the dead car battery when needed the most.
Conversions between electrical units are usually simple and straightforward - take a formula, write down values, and let the calculator do the rest.
However, in real life, things are not always that simple, especially when converting units that require at least one unit to be known. If You wish to know more about converting watts to amps, amps to watts, volt-amps to watts, and similar, read carefully...
Many people wonder what is the required size of the power generator in order to run an air conditioner without any power issues.
2000-watt inverter generators are popular, compact, and affordable portable units that are used in many situations, leading to the question, will a 2000 watt generator run an air conditioner in the case of a power outage?
Lithium electric trolling motor batteries offer many advantages over lead-acid batteries, including lightweight design, a large number of charging/discharging cycles, a very low self-discharge rate, more constant output voltage, almost no capacity loss with the current increase, etc.
Also, lithium trolling batteries still have some issues, like high initial price and safety concerns. For safety reasons, lithium trolling motor batteries are almost exclusively Lithium Iron Phosphate (LiFePO4) batteries featuring built-in Battery Management Systems (BMS), protecting the battery from unwanted events like short circuit, overcharge, over-discharge, and similar.
Portable generators with 120/240V 50A (14-50R) plug and the list of other ports (L14-30R, L5-30R, 5-20R, 12VDC, etc.) are large, sturdy and powerful units, capable of providing plenty of energy over a longer period of time.
50 Amp portable generators are often used as RV generators, camping generators, in emergencies, on the construction sites and similar. They are usually powered by gas or gas/propane combination (dual-fuel models), with some larger industrial/commercial models featuring diesel engines.
2000 watt generators are a very popular class of power generators, featuring acceptable price, long runtime on a single gas tank, quiet operation, simple maintenance etc., and are thus often used for camping, boating, fishing trips, in RVs, etc. Also, they are often used in emergencies.
Thus, many people wonder what household appliances their 2000 watt power generators may run and for how long.
When powering home appliances using power generators and power stations, it is of utmost importance to know how much power our appliances require in order to operate properly and to avoid issues of overloading the power generators and power stations.
Our appliances chart includes the most common appliances, tools, gadgets used at homes, RVs, on the boats/yachts, during camping, etc.
Many people wonder if the car battery can die while driving, especially after their car battery died while driving. Obviously, answer is 'Yes, a car battery can die while driving'.
A cood car starting or dual purpose battery should not die while driving, but although it is rare event, it happens. There are many reasons why a car battery dies while driving, here are the few most common ones...
Most cars still use lead-acid batteries of some kind - wet/flooded, AGM or even Gel-cells, but these batteries over time lose their capacity and the ability to start the engine.
Since quality car batteries are not cheap, many people wonder how they can recondition a car battery at home. Reconditioning car batteries at home can be done successfully, but this also depends on the battery type, its use, age, current condition and similar.
Solar panel kits are great solution for powering hungry electric and electronic devices in various off-the-grid situations like camping, taking fishing trips, or simply when having issues with mains power.
Solar panel kits consists of one or more solar panels, power/charge controller and one or more deep cycle batteries for storing electric energy and are usually combination of solar panel/power (charge) controller/battery or solar panel/power station.
Battery powered sump pumps are type of emergency equipment that must operate reliably when required, and saving the money on these pumps or their batteries may be very expensive thing to do.
Sump pump backup battery must be strong enough to power sump pump motor and it must store enough energy to power the whole unit long enough to prevent as much damage as possible until mains power is restored.
Knowing your car's battery amps and other features is very important not only when replacing the battery, but also when the battery is being used not only for cranking purposes, but also for powering other electric and electronic systems like lights, navigation, multimedia devices, security systems, etc.
With more and more onboard systems, car manufacturers are slowly replacing pure starting batteries with the new dual purpose AGM batteries, featuring many improvements over older flooded ones.
Non-Rechargeable (disposable) zinc-air batteries have been standard hearing aid batteries for a long time. They have replaced older mercury-oxide batteries and after introducing mercury-free zinc-air batteries, they have become de facto standard for hearing aid batteries.
However, rechargeable batteries are being used more and more in everyday electronics and as such, they are slowly entering the hearing aid market as well. But, there are several very important issues that rechargeable batteries face when being used as hearing aid batteries...
Wrist watches are commonly powered using one or rarely two button/coin cell batteries, and these batteries have a limited operating lifetime. When replacing an old battery with the new one, the best practice is to use batteries recommended by the watch manufacturers.
However, finding the exact type and model can be sometimes confusing due to the different labels some battery brands are using for their batteries. Also, using silver-oxide instead of alkaline batteries can prolong the watch operating time on a single battery.
Marine batteries are designed to operate in tough conditions due to vibrations and other mechanical stress, they must be able to power various electric and electronic devices and when the main engine must be started, they must be able to provide large currents in order to start large, often multiple gasoline or even diesel engines even when not fully charged. Such requirements significantly reduce the number of potential 1000 CCA marine battery models.
CCA (Cold Cranking Amps), CA (Cranking Amps) or MCA (Marine Cranking Amps) and HCA (Hot Cranking Amps) define the maximum current that a battery is able to provide under certain conditions.
With all the available battery models and brands on the market, finding suitable trolling motor battery often can be daunting task, but it shouldn't be. But before getting new battery or battery pack, one should first write down few things, including size and weight of the boat, motor strength, required trolling time and of course, the funds allocated for the new trolling motor battery.
When describing batteries and their features and characteristics, many abbreviations are used.
Knowing their meanings is very important, because that is the difference between getting the right battery and the wrong battery. And the wrong battery often can cause much more damage than its money worth ...
Deep cycle batteries for recreational vehicles (RVs) have very important purpose - they power onboard electronics and electrical devices while the vehicle's main motor is not working, while being off the grid. RV deep cycle batteries must tolerate deep discharge conditions and cyclic use, but they also must be resistant to vibrations, high and low temperatures, no usage for long time (sometimes for months) etc.
And since these batteries are far from being cheap, it is really important to choose them properly, according to the individual needs and requirements.
